Yes indeed it might happen today - can you give me a little echo chamber there. . .
Shep starts by playing various radio and commercial theme songs on the kazoo and the reminiscing old high school songs.
Shep talks about working as a 'combination man' for a radio station where he performs multiple duties such as being the engineer, having to fix broken equipment, selling commercial time to local stores, and being all the different on air personalities.
He would introduce a man on the street show and while the theme music was playing, run down to the street, do the interviews and then run back up to the studio to do another show such as "Bing Sings", as a different personality. Then he would put a long record on and run to the local hardware store and pitch for them to buy commercial time, getting back to the studio just in time for the end of the record.
One of his great mistakes was closing out the end of the day, while speaking to someone on the phone, he puts on the French National Anthem in error. The phone go crazy before he realizes what he has done.
This is one of at least 60 shows that were recorded for syndication sometime in late 1964 / early 1965. There were gaps left for commercials to be inserted.
